Mount Bromo is one of the most beautiful and most famous volcanoes in Indonesia. It is located in Tengger, in East Java. It was created following an enormous eruption. The eruption created a huge caldera. A caldera is a large volcanic crater, typically one formed by a major eruption leading to the collapse of the mouth of the volcano. This caldera created the active volcano Mount Bromo and the non-active volcano Mount Batok. In a few million years I predict that Mount Bromo will become a much bigger volcano. Since Mount Bromo is an active volcano whenever it erupts the magma will add onto the volcano.
